Description

Technical Field

[0001] This utility model relates to the technical field of double-net wet slurry machine, specifically to a dewatering frame for a double-net wet slurry machine. Background Technology

[0002] With the rapid development of my country's pulp and paper industry, the scale of paper production has continued to expand, and the requirements for pulp output of single equipment have been increasing. Among them, the double-wire wet pulp mill is a key piece of equipment in the paper industry, mainly used for pulp dewatering and forming processes. The gravity dewatering zone, as an important component of the double-wire wet pulp mill, removes water from the pulp through gravity, laying the foundation for subsequent pressing and drying stages.

[0003] However, the gravity dehydration zone in the existing technology has obvious defects. Specifically, the monolithic structure results in fixed equipment size, which is difficult to adapt to the space constraints of different sites or production lines. At the same time, after the gravity dehydration zone is installed, it is extremely inconvenient to adjust its height or lateral position, which ultimately leads to a decrease in dehydration efficiency, uneven product quality, and even increased maintenance frequency and production costs. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a dewatering frame for a double-net wet pulp machine, thereby reducing the frequency of maintenance and production costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a dewatering frame for a double-net wet pulp machine, including: a frame body, an adjustment component, and multiple dewatering modules; The frame body has an installation cavity for multiple dehydration modules. The multiple dehydration modules are arranged sequentially along the length of the frame body and connected to the installation cavity through adjustment components. There are multiple adjustment components, and each dehydration module is provided with one adjustment component. The adjustment assembly includes a horizontal adjustment plate, a vertical adjustment plate, and an adjustment screw. The vertical adjustment plate is disposed on the dehydration module. The adjustment screw is fixed to the vertical adjustment plate and threadedly connected to the horizontal adjustment plate. The adjustment screw is used to adjust the distance between the vertical adjustment plate and the horizontal adjustment plate to adjust the height of the dehydration module. The horizontal adjustment plate has multiple sets of fixing holes arranged along the width direction of the frame body. The horizontal adjustment plate is connected to the frame body by bolts engaging with the fixing holes.

[0006] In some embodiments, the fixing holes are arranged in multiple rows along the width direction of the frame body.

[0007] In some embodiments, the multiple rows of fixing holes include two rows of fixing holes.

[0008] In some embodiments, there are multiple adjusting screws that penetrate vertically through the vertical adjusting plate.

[0009] In some embodiments, the vertical adjustment plate and the dehydration module are fixedly connected by welding or bolts.

[0010] In some embodiments, the lateral adjustment plate is detachably connected to the frame body by bolts.

[0011] In some embodiments, multiple dehydration modules each have a dehydration surface facing away from the ground, and when the multiple dehydration modules are installed into the mounting cavity, the multiple dehydration surfaces are all on the same plane.

[0012] In some embodiments, the width of the dehydration module ranges from 1 meter to 2 meters.

[0013] In some embodiments, the frame body has a clearance groove to avoid the adjusting screw, and the lateral adjusting plate covers the clearance groove.

[0014] Furthermore, the beneficial effects of this utility model are as follows: This invention, by setting up multiple dewatering modules, has configured the gravity dewatering area into a segmented structure. It also incorporates an adjustment component that allows for independent and precise adjustment of the height and lateral position of each dewatering module, ensuring a smooth and uniform surface in the dewatering area and preventing uneven dewatering of the slurry. This design reduces the size and weight of individual components, making transportation and handling more convenient and adaptable to different production sites. It also improves the flexibility and maintainability of the equipment, reduces downtime due to adjustments or repairs, and enhances overall production efficiency and product quality stability, ultimately achieving a low-cost, highly adaptable dewatering zone.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. In the description of the embodiments of the present utility model, unless otherwise stated, " / " means "or", for example, A / B can mean A or B; "and / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. In addition, in the description of the embodiments of the present utility model, "multiple" means two or more. Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this utility model, unless otherwise stated, "multiple" means two or more.

[0018] like Figure 1 - Figure 2 As shown, this utility model provides a dewatering frame for a double-net wet pulp machine, including: a frame body 1, an adjustment component, and multiple dewatering modules 2; The frame body 1 has an installation cavity for multiple dehydration modules 2. The multiple dehydration modules 2 are arranged sequentially along the length of the frame body 1 and connected to the installation cavity through adjustment components. There are multiple adjustment components, and each dehydration module 2 is provided with one adjustment component. The adjustment assembly includes a horizontal adjustment plate 5, a vertical adjustment plate 3, and an adjustment screw 4. The vertical adjustment plate 3 is mounted on the dewatering module 2. The adjustment screw 4 is fixed to the vertical adjustment plate 3 and threadedly connected to the horizontal adjustment plate 5. The adjustment screw 4 is used to adjust the distance between the vertical adjustment plate 3 and the horizontal adjustment plate 5 to adjust the height of the dewatering module 2. The horizontal adjustment plate 5 has multiple sets of fixing holes 6 arranged along the width direction of the frame body 1. The horizontal adjustment plate 5 is connected to the frame body 1 by bolts and fixing holes 6. The frame body 1 has a clearance groove to avoid the adjustment screw 4. The horizontal adjustment plate 5 covers the clearance groove.

[0019] In the above structure, during use, the frame body 1 is first placed in the predetermined position on the production line, and the installation cavity is checked to ensure it is clean and free of debris to ensure smooth subsequent installation. Then, according to production needs, multiple dewatering modules 2 are selected for installation. During installation, the vertical adjustment plate 3 is connected to each dewatering module 2 by welding or bolt fixing. Then, the horizontal adjustment plate 5 is connected to the frame body 1 by bolts. The horizontal adjustment plate 5 is provided with multiple sets of fixing holes 6 arranged along the width direction of the frame body 1, such as two rows of fixing holes 6. The user selects different fixing holes 6 to insert bolts according to actual needs to adjust the horizontal position of the dewatering module 2 to adapt to the width change of the pulp screen. At the same time, during the above installation process, the adjusting screw 4 is fixed to the vertical adjustment plate 3 and threadedly connected to the horizontal adjustment plate 5. By turning the adjusting screw 4, the distance between the vertical adjustment plate 3 and the horizontal adjustment plate 5 can be precisely controlled, thereby changing the height of the dewatering module 2 until all dewatering surfaces are coplanar, ensuring uniform gravity dewatering.

[0020] Furthermore, if adjustments are needed during dewatering or use based on pulp characteristics or equipment wear, these adjustments can be made by adjusting the positions of the vertical adjustment plate 3 and the horizontal adjustment plate 5, without disassembling the entire dewatering zone. This design not only simplifies the installation and maintenance process but also improves the adaptability and reliability of the equipment, making it suitable for various paper production environments.

[0021] The above-mentioned design of this utility model reduces the size and weight of individual components, making transportation and handling more convenient and adaptable to the needs of different production sites. At the same time, it improves the flexibility and maintainability of the equipment, reduces downtime caused by adjustments or maintenance, improves overall production efficiency and product quality stability, and ultimately achieves a low-cost, highly adaptable dehydration zone solution.

[0022] In one possible implementation, the fixing holes 6 are arranged in multiple rows along the width direction of the frame body 1. The multiple rows of fixing holes 6 include two rows of fixing holes 6, which ensures sufficient adjustment range and simplifies the structure, reduces manufacturing costs and complexity, and improves the practicality and economy of the equipment.

[0023] In one possible implementation, there are multiple adjusting screws 4, which vertically penetrate the vertical adjusting plate 3. This enhances the stability and uniformity of height adjustment, prevents the dehydration module 2 from tilting or shaking during operation, and ensures the force balance in the dehydration zone.

[0024] In one possible implementation, the vertical adjustment plate 3 and the dehydration module 2 are fixedly connected by welding or bolts, which enhances the stability between the adjustment plate and the dehydration module 2.

[0025] In one possible implementation, the lateral adjustment plate 5 is detachably connected to the frame body 1 by bolts, which facilitates installation, adjustment and replacement.

[0026] In one possible implementation, multiple dehydration modules 2 each have a dehydration surface facing away from the ground. When the multiple dehydration modules 2 are installed into the installation cavity, the multiple dehydration surfaces are all on the same plane. Specifically, during the adjustment process, a level is used to check whether the dehydration surfaces of the multiple dehydration modules 2 are on the same plane. If there is a deviation, the adjusting screw 4 is finely adjusted.

[0027] In one possible implementation, the width of the dehydration module 2 is between 1 meter and 2 meters, and is preferably 1.5 meters in this invention.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
